| * USB: Force unbinding of drivers lacking reset_resume or other methodsAlan Stern2008-07-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1024) takes care of a FIXME issue: Drivers that don't have the necessary suspend, resume, reset_resume, pre_reset, or post_reset methods will be unbound and their interface reprobed when one of the unsupported events occurs. This is made slightly more difficult by the fact that bind operations won't work during a system sleep transition. So instead the code has to defer the operation until the transition ends.

| * USB: fix usb_reset_device and usb_reset_composite_device(take 3)Ming Lei2008-07-211-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch renames the existing usb_reset_device in hub.c to usb_reset_and_verify_device and renames the existing usb_reset_composite_device to usb_reset_device. Also the new usb_reset_and_verify_device does't need to be EXPORTED . The idea of the patch is that external interface driver should warn the other interfaces' driver of the same device before and after reseting the usb device. One interface driver shoud call _old_ usb_reset_composite_device instead of _old_ usb_reset_device since it can't assume the device contains only one interface. The _old_ usb_reset_composite_device is safe for single interface device also. we rename the two functions to make the change easily. This patch is under guideline from Alan Stern.

These operate at either high or full/low speeds and at a given bMaxPower. - struct usb_composite_driver ... groups one or more such configurations into a gadget driver, which may be registered or unregistered. - struct usb_composite_dev ... a usb_composite_driver manages this; it wraps the usb_gadget exposed by the controller driver. This also includes some basic kerneldoc. How to use it (the short version): provide a usb_composite_driver with a bind() that calls usb_add_config() for each of the needed configurations. The configurations in turn have bind() calls, which will usb_add_function() for each function required. Each function's bind() allocates resources needed to perform its tasks, like endpoints; sometimes configurations will allocate resources too. Separate patches will convert most gadget drivers to this infrastructure. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
| * usb gadget: descriptor copying supportDavid Brownell2008-07-211-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Define three new descriptor manipulation utilities, for use when setting up functions that may have multiple instances: usb_copy_descriptors() to copy a vector of descriptors usb_free_descriptors() to free the copy usb_find_endpoint() to find a copied version These will be used as follows. Functions will continue to have static tables of descriptors they update, now used as __initdata templates. When a function creates a new instance, it patches those tables with relevant interface and string IDs, plus endpoint assignments. Then it copies those morphed descriptors, associates the copies with the new function instance, and records the endpoint descriptors to use when activating the endpoints. When initialization is done, only the copies remain in memory. The copies are freed on driver removal. This ensures that each instance has descriptors which hold the right instance-specific data. Two instances in the same configuration will obviously never share the same interface IDs or use the same endpoints. Instances in different configurations won't do so either, which means this is slightly less memory-efficient in some cases. This also includes a bugfix to the epautoconf code that shows up with this usage model. It must replace the previous endpoint number when updating the template descriptors, not just mask in a few more bits.

| * USB: implement "soft" unbindingAlan Stern2008-07-211-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1091) changes the way usbcore handles interface unbinding. If the interface's driver supports "soft" unbinding (a new flag in the driver structure) then in-flight URBs are not cancelled and endpoints are not disabled. Instead the driver is allowed to continue communicating with the device (although of course it should stop before its disconnect routine returns). The purpose of this change is to allow drivers to do a clean shutdown when they get unbound from a device that is still plugged in. Killing all the URBs and disabling the endpoints before calling the driver's disconnect method doesn't give the driver any control over what happens, and it can leave devices in indeterminate states. For example, when usb-storage unbinds it doesn't want to stop while in the middle of transmitting a SCSI command. The soft_unbind flag is added because in the past, a number of drivers have experienced problems related to ongoing I/O after their disconnect routine returned. Hence "soft" unbinding is made available only to drivers that claim to support it. The patch also replaces "interface_to_usbdev(intf)" with "udev" in a couple of places, a minor simplification.
